Detailed Description

template<class Functor, typename FType>
class CompactificationL< Functor, FType >

Transform arbitrary function so that its definition range will be \( t \in [-1,1] \), for original interval \( x \in [a,b] \). The following formulas are used:

\[ x = b - L \frac{1+t}{1-t} \Leftrightarrow t = \frac{x - b + L}{x - b + L} \ . \]

Note that in this case the monotonic character is reverse.
